I have a sweet spot for rangefinder cameras. I don’t know if it’s their simplistic styling, their boxy look, their reliance on metal and leather as essential design elements, or something else I can’t quite put my finger on. But whatever it is, videos like this one by Ilott Vintage — the company who restores vintage rangefinder cameras — only serve to increase my obsession.

Ilott Vintage focuses on restoring select vintage cameras that are entirely mechanical; everything in the camera runs on gears, levers and springs. Check out the video below for a look at some jaw dropping mid-century engineering.
